About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X250S
The MGCD32X250S is a JIS-standard round-body mini cylinder, double acting, with a double rod and a variable air cushion at both ends. A 12 mm hard-chrome-plated rod exits each cover with the same M10x1.25 male thread, so the two rod ends move together and the output force is equal in both directions: about 345.6 N each way at 0.5 MPa and 483.8 N at 0.7 MPa, because both sides of the piston work on the rod-side area. The adjustable cushion decelerates the piston smoothly at each end of the 250 mm stroke, allowing higher travel speeds and heavier loads than an unbuffered cylinder. The fitted magnet (S code) enables CMSG, DMSG or EMSG switches for end-position sensing.
Built around a riveted SUS304 stainless barrel with hard-chrome-plated carbon-steel rods and a two-way lubricant-storing piston seal, this 32 mm bore cylinder runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi), a temperature range of -20 to +70 C and speeds of 30-800 mm/s. As a practical sizing rule, apply about 0.6 of the rated force, so plan on roughly 21 kg of safe vertical load. The rear rod end can carry a stop flag, a second fixture or a position indicator while the front rod does the work.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X250S Is Used
High-speed anti-rotation transfer
The through-rod resists rotation while the variable air cushion absorbs the momentum of fast 30-800 mm/s travel, letting a 345.6 N push-pull slide move parts between stations without hard stops or drift.
Twin-load press with soft stop
Equal 483.8 N force at 0.7 MPa on both rod ends lets one cylinder press or stake two light workpieces in line, with the adjustable cushion easing the ram down at each end to protect tooling.
Rear-switch slide with position flag
The rear rod end carries a stop or flag picked up by CMSG or DMSG switches on the magnet-fitted barrel, giving a 250 mm stroke slide with cushioned ends and reliable end-position feedback.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X250S the Right Cylinder?
Size the MGCD32X250S by force, not bore alone: this 32 mm bore delivers 345.6 N each way at 0.5 MPa, sitting between the 25 mm bore (206.1 N) and the 40 mm bore (527.8 N). If your load needs more, step up to MGCD40; if less, MGCD25 saves space. Choose this model when you need a through-rod with equal force both directions plus adjustable cushioning at both ends; if you only need a fixed bumper pad on a double-rod cylinder up to 40 mm bore, the MGD is the lighter option, and for a single rod with a cushion the MGC is the equivalent. The 250 mm stroke is within the 500 mm maximum standard stroke for this bore. Mount with the LB foot or FA flange, and add I or Y rod knuckles on the rod ends; SDB and CB mounts are not available on this family. The fitted magnet means CMSG, DMSG or EMSG switches can be clipped on for position feedback. For long strokes like this one, support the load carefully and avoid side loading on the 12 mm rod, or guide the load externally.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X250S FAQ
Because the double rod exposes the rod-side area on both sides, the force is equal both ways: 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa, with a theoretical maximum of 70.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -20 to +70 C, speed range is 30-800 mm/s, and the fluid is air filtered to 40 um. Air ports are 1/8" and the rod thread is M10x1.25 on both ends.
The MGCD32X250S has an adjustable air cushion at both ends that decelerates the piston near each end of the stroke, so you can run higher speeds or carry heavier loads without metal-to-metal impact; it is an air brake for stopping, not a lock, so use an external rod lock or pilot check valve if the load must be held on air loss. Unlike the MGD, which is a double-rod cylinder with fixed bumper pads, the MGCD cushions are adjustable. Unlike the single-rod MGC, the MGCD's through-rod gives equal force in both directions and a rear rod end for a stop flag or second load. The fitted magnet also accepts CMSG, DMSG or EMSG switches.
